Answer:
= -1.984 Diopters
Explanation:
The lens should form an upright, virtual image at the far point.
Therefore;
The image distance, V will be -50.4 cm, since the image is virtual.
For objects at very far distant the object distance,u, will be ∞ ; This means that focal length, f, will be equivalent to image distance, v, that is -50.4 cm
Therefore; f = -50.4/100 = -0.504 m
But, since Power of a lens, P, is given by the reciprocal of focal length in meters, (1/f)
Then, power will be given by;
Power = 1/f
= 1/-0.504 m
=- 1.984
Power is measured in Diopters
Hence <u>= -1.984 Diopters</u>
Answer:
Fc=5253
N
Explanation:
Answer:
Fc=5253
N
Explanation:
sequel to the question given, this question would have taken precedence:
"The 86.0 kg pilot does not want the centripetal acceleration to exceed 6.23 times free-fall acceleration. a) Find the minimum radius of the plane’s path. Answer in units of m."
so we derive centripetal acceleration first
ac (centripetal acceleration) = v^2/r
make r the subject of the equation
r= v^2/ac
ac is 6.23*g which is 9.81
v is 101m/s
substituing the parameters into the equation, to get the radius
(101^2)/(6.23*9.81) = 167m
Now for part
( b) there are two forces namely, the centripetal and the weight of the pilot, but the seat is exerting the same force back due to newtons third law.
he net force that maintains circular motion exerted on the pilot by the seat belts, the friction against the seat, and so forth is the centripetal force.
Fc (Centripetal Force) = m*v^2/r
So (86kg* 101^2)/(167) =
Fc=5253
N
Answer:
C. Heat
Explanation:
HEAT is energy that is transferred due to a difference in temperatures.
I hope it helps! Have a great day!
Answer:
The angle of the corresponding refracted ray is 34.84°
Explanation:
Given that,
Refractive index of water n= 1.33
Refractive index of glass n= 1.52
Incident angle = 30.0°
We need to calculate the refracted angle
Using formula of Snell's law

Put the value into the formula





Hence, The angle of the corresponding refracted ray is 34.84°
It goes in the downward direction
